While stopped in traffic, upon acceleration. engine stalled. vehicle placed in park and car was restarted and driven away. main fuel relay was replaced. per acura service bulletin 01-044, the incident that occurred could be due to a failed powertrain control module. per acura service bulletin 01-044, there was an updated powertrain control module, but this part has since been discontinued and is no longer being produced by acura. i have called acura customer service who stated that even though they are aware of the circumstances per technical service bulletin 01-044, there is nothing they are able to do to repair the car. i feel that this is a safety related issue due to the risk that the vehicle has the potential to continue to stall and cannot be repaired. *tr
